Deskripsi
CTLA-4 is critical for balancing protective immunity with self-tolerance. Here the authors identify homozygous DEF6 mutations in patients with severe autoimmunity, one of which received and responds to CTLA-4-Ig, and show that DEF6 is crucial for CTLA-4 cell surface trafficking and immune regulatory function.
